Numerical expressions are math problems containing only numbers and operational symbols. Solve by first completing any computations appearing inside parenthesis, working from left to right. Then compute exponents, working from left to right. Finally, complete the multiplication and division portions from left to right, followed by the remaining addition and subtraction portions.Continue Reading
Find the value of any portions of the numerical expression that are located inside parenthesis. Compute these values by working from left to right inside the parenthesis, doing multiplication and division first and addition and subtraction second. For example, compute (2 + 4) x (15 - 6 x 2) by first simplifying 2 + 4 to get 6 x (15 - 6 x 2) and then computing 6 x 2 to get 6 x (15 - 12). Finish computing the portion in the parenthesis by doing the subtraction to get 6 x 3.
Compute the actual value of any number in the numerical expression that has an exponent. For example, convert 2^2 to 4.
Working from left to right, compute any multiplication and division found within the numerical expression. Using this method, the expression 4 x 6 + 2 x 4 becomes 24 + 8.
Finish the problem by completing the addition and subtraction, again working from left to right. This gives the solution to the numerical expression.
Use formulas to solve problems by substituting numbers or expressions for the variables. This can entail rearranging the formula so that the required variable is on one side of the equation.Full Answer >
Exponential math is any mathematical operation involving an exponent, which is the number or symbol placed above and after another number or symbol to indicate the power to which the former number is to be raised, Wikipedia explains. The operation 4 x 4, for example, is written exponentially as 4^2.Full Answer >
In mathematics, the term "multiplier" pertains to any number by which another number, known as the "multiplicand," is multiplied. The result of a multiplication operation is referred to as the "product."Full Answer >
Four squared in math is 16, as any number squared is multiplied by itself. Another way to express four squared is to say four to the second power.Full Answer >
